GUN WITH REG'OILING BARREL.

Specification of Letters Patent.

Patented May as, 1907.

Application med June 22,1906. Serial Nb. 322,902.

many, have invented certain new and useful Improvements in Guns vrels;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to improvemcntsin guns with recoiling barrel andhas for its obwith Recoiling Barject to -construct the gun so as to beable to,

While the forward motion spring may remain with in the cradle in thenecessary initial tension. For this purpose a disk is inserted between aflange of the brake cylinder and the end of the.forward motion springabutting against said flange, which disk after the removing of the brakecylinder abuts against a flange of the cradle and secures thereby theforward motion spring in the cradle. flange of the cradle may beconstructed so as to serve as atension screw for the forward motionspring. Instead of this however the flange of the brake cylinder mayserve for the said purpose in the manner heretofore known.

My invention is adapted essentially for guns which must be transportedin single parts and wherein it is desirable or prescribed to have theweight of the parts within certain limits. In the known guns withrecoiling barrel it is necessary for removing the brake cylinder toloosen a tension nut and then to remove the spring from the cradle. Ifthe whole is then remounted the spring must be brought again undertension. All this requires much time and labor.

In the accompanying drawings Figure 1 is a sectional side elevation of agun constructed according to my present invention. Fig. 2 is alongitudinal section through the fore end of the cradle, the brakecylinder being removed. Fig. 3 is a similar section showing amodification with the brake cylinder in its place. i

In the construction shown by Fig. 1 and 2 the brake cylinder a isfastened in a wellknown manner to the'horn b of the barrel 0. At itsfore end the brake cylinder a is proremove the brake cylinder out of thecradle,

The

vided with a flange d, against which the forward motion spring e abutsby means ofa loosely inserted disk The latter is supported at the sametime against a flange g of a sleeve h provided with a screw thread on1ts outer surface and screwed mto a female sleeve lc'fastened in thecradle i.

It will be seen, that during the recoil of the gun barrel and of thebrake cylinder the spring a is compressed by the flange d and the diskf, when the spring by pressing on the disk brings the brake cylinder andthe gun barrel back to their initial position.

If it is required to remove the brake cylinder the fore cover Z of thecradle is opened and the brake cylinder disconnected from the horn b ina well known manner. Then the brake cylinder is Withdrawn from the foreend, when .the spring 6 being under an initial tension presses the diskfagainst the flange g thereby being held securely within the cradle. Thesleeve his a screw for bringing the spring under a desired tension, thistension being maintained also if the brake cylinder is removed.

In the modification shown by Fig. 3 the flange dis not provided directlyon the brake cylinder but on a sleeve m serving as a tension screw forthe spring a and screwed. on to the brake cylinder. E

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare,that What I claim is:

1. In a recoil brake for guns, a detachable recoil cylinder, a stopcarried by the cylinder, a loose disk bearing upon the stop, a forwardmotion spring bearing upon the'disk to return the parts after recoil,and a stop carried by the cradle in the path of the disk and independentof the cylinder to limit the relaxation of the sprin 2. In a recoilbraIce for guns, a cradle, a detachable recoil cylinder within thecradle,

. a stop carried by the cylinder, a loose 'disk bearin upon the stop, aforward motion spring bearing upon the disk, and a stop carried by thecradle to limit the relaxation of the spring, the two stops lying insubstantially the same plane transversely of the cylinder.

3. In a recoil brake for guns, a recoil member'moving with the gun, aforward motion spring bearing withone end on a fixed abutment and withthe other end on the recoil member, and means interposed in the path ofthe relaxing spring to limit the movement of the same when the recoilmember is withdrawn.

4:. In a recoil brake for guns, a cradle, a forward motion spring withinthe cradle bearing with one end against a fixed support, a detachablerecoil member movable within the cradle and surrounded by the spring, astop carried by the recoil member and serving as an abutment for theother endof the spring during recoil, a loose disk between the recoilmember stop and spring, and an adjustable stop on the cradle in .thepath of the relaxing spring to engage the disk when the recoil member iswithdrawn.

r 5. In a gun with recoilin barrel the combination with a cradle of arake cylinder, a forward motion spring, a flange on the brake cylinder,a loose disk between this flange and the forward motion spring and aflange connected with the cradle and serving as a supportfor the saidloose disk if the brake cylinder is removed, substantially as describedand for the purpose set forth.

6. In a gun with reeoiling barrel the combination with a cradle of abrake cylinder, a a flange on the brake the forward motion spring, asleeve screwed into the cradle and a flange connected with this sleeveand serving as a support for the said loose disk if the brake cylinderis removed, substantially as described-and for the purpose set forth.

In testimony whereof I have aflixed my signature to this specification,in the presence of two witnesses.
